I have a harmonic balancer puller to try and get my crank pulley off. I'm in the middle of a timing belt change. The pulley won't come off freely. (Yes the 19mm bolt is removed lol) What size bolts do i need to attach the puller to the pulley? I've tried two kits and neither had the right threads! Help!!!

They are 8mmx1.25. You'll need bolts long enough to reach the very back of the pulley, because only the rear part of the holes are 8mm and threaded (maybe the last 1/4" or 3/8" at the back of the holes). The front end of the holes are 10mm (or just under, because a 3/8" bolt fits in there) and are not threaded. The front part of the holes are used to insert the crank pulley holding tool, when removing or installing the crank bolt.

Don't beat yourself up... it's a common mistake! Good luck with the rest of the job. Make sure you get the crank bolt torqued back up properly to 217 ft-lb (I also used blue loctite on the crank bolt threads to give me a bit more assurance that it won't back out). Take your time putting the belt back on and make sure you're timing marks are all lined up properly before closing everything back up. Other than that, you should be good to go.
